Install G&P Vltor MOD stock on G&G M4 Blowback
 

Recently I purchased G&P Vltor MOD Buttstock, but I do not know how to install the stock to my G&G M4 Blowback. I suspect the Vltor buffer tube is not compatible with my gun. Would anyone know any additional items I would need to put the buttstock securely on my gun?

I just don't see how the G&P lock nut + the shorter screw could securely attach to the G&G upper receiver.

I advise looking at Huang's parts thread, he has instructions on how to do it. I purchased one from him and I had to cut two inches IIRC from the buffer tube.

The G&G blowback receivers are slightly different than standard. The piece on the rear of body that the buffer tube slides onto is "flat" on the bottom, whereas standard receivers are round. I'm not sure if this will cause a problem with your install, but just be aware.

Is it feasible to super glue the Vltor buffer tube onto the back of the receiver?

I always thought that there were two types of armalite receivers. Ones for rear wiring with crane stocks and sliding stocks and ones for front wiring and full stocks or at least that is what I have come to notice from dealing with G&P and King Arms products, this probably is not the case for all companies though.

Just have a glance here at the G&P website

You will notice two types of receivers. A regular and a (B type), notice how on the (B type) the stock tube is significantly shorter? You may require to cut off some of your stock tube in order for your buffer tube to fit.

Go sit in the corner for 10 minutes and think about what you have said.

I think this i was you need to do...

Since you were not entirely clear on your compatibility issue I just wanted to toss this in there to cover all possibilities just in case your buffer tube slides onto the stock tube but wobbles.

If the buffer tube is sliding fully onto the stock tube but wobbling you could always attempt to fill up the difference with some grip tape or something. Unless you feel like coating your stock tube in JB weld and painstaking grinding and filing it to the correct size.

Glue is not an option because if you were to ever rear wire or decide to change to a single point rear plate sling; a glued on buffer tube would be a nightmare.

Well, using superglue it would not change a thing.

But it would not hold at all either. Superglue does not do anything to metals... so you will get a bunch of glue sticked to the prong and the buffer tube wall will just get loose.

Read the instructions up there. It will be all you need to do.
